Hi, Andreas
Thank you your reply.
This problem was solved.
I revalidated your advice, source code and the statistics.
As a result, the cost was changing due to the difference in the index height.

t each index were the same.
We did not rebuild or update indexes.
What are the reasons why the index has been changed besides the following
factors?
- cost values
- Index creation order
PostgreSQL version : 9.5.2
